Teaching Reform of the Mechanical Drawing Course Incorporating Computer Graphics Technology

With the development and popularization of computer application technology, the use of computer graphics and image processing technology has become the main means of modern engineering design and drawing. Learning and mastering 3D modeling technology and mechanical information modeling technology have become an important goal of learning engineering drawing. To meet the teaching requirements of the “New Engineering” program, higher education should cultivate innovative talents with the ability to identify, express, analyze, and solve complex engineering problems; promote the transformation of teaching methods for the course of “Mechanical Drawing and Computer Drawing” from “teaching well” to “learning well.” This change is not only a change in course content, but also a change in training objectives. It introduces modern 3D design concepts into the drawing course, constructs a learning system with 3D modeling technology as the main line, solves the problem of imagination in traditional teaching, makes the learning process more in line with scientific cognitive laws, better meets the needs of modern manufacturing industry for new technologies, and improves students’ drawing skills and ability to use modern tools (computer drawing).
